ACETYLENE-GAS LAMP.

Specification of Letters Yatent.

Application led May 24, 1911. Serial No. 629,203.

To all whom it may concern:

Be it known that I, LORENZO EVANS, a citizen of the United States,residing at Hiteman, in the county of Monroe and State of Iowa, haveinvented new and useful Improvements in Acetylene-Gas Lamps, of whichthe following is a specification.

The invention relates to acetylene generators and has for an object toprovide an acetylene lamp for producing light.`

Among other features my device embodies a lamp adapted to employ carbidand Water to produce a gas, the lampbeing so arranged that when thecarbid container is removed therefrom to refill the container, the lampwill still be operative to produce a light.

In a large number of acetylene lamps now 'in use, when the carbidcontained in the main carbid container becomes exhausted, the containermust be withdrawn from the lamp and refilled with carbid to produce newgas and in the meantime the light at the burner of the lamp will beextinguished so that if there is no other light present the operatorwill be in the dark. In my device the lamp is so arranged that a lightwill be produced at all times, evenwhen the main carbid container isbeing refilled with carbid to generate a new gas.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is avertical sectional view of my device. Fig. 2 is a horizontal section onthe line 2.-2 in Fig. 1, looking in the direction of the arrow. Fig. 3is a fragmentary' partment 15 being adapted to contain wa-V ter and thecompartment 16 being adapted to contain carbid and constitute anauxiliary carbid-container, a cover 17 belng thread- -edly connected tothe cover 12 so that carbid can be placed thecompartment 16. A

valve 22 adapted to rest on the 'valve seat 20 and the upper end of thesaid rod is threaded for. engagement with a head 23 of the tube 18, aknob 24 being secured to the outer end ofthe rod 21. An auxiliary watertube 25, similar to' thetube 18, extends from the cover 12 through theWater compartment 15 and the partition 14 into the auxiliary carbidcontainer 16, the said tube being provided atthe lower end with a valveseat 26 similar to the valve seat 20 and extended through the said tubeis a rod 27 having the lower end pointed to form a needle valve' 28 and:the upper end provided with a knob 29 and threadedly engaging the tube25, the said tube being provided with a series of apertures 30. A

burner 31 extends outwardly from the bodyY 10 and an auxiliary burner 32extends outwardly from the compartment 16, Vthe burner 31 having an endterminating at the indented portion of the body 10 .to receive gasgenerated in the container 11.

In the operation of my 'device carbid is placed in the carbid container11 and in the auxiliary carbid container designated by the numeral landwater is poured into the water compartment 15. Now by turning the knob24, the needle valve 22 will be op-v erated, thus permitting water toflow from the compartment 15 through the apertures 19in the tube 18 anddownwardly into the carbid container 11, the mixture of carbidv andwater being adapted to produce gas in the usual manner which poursoutwardly ythrough the burner 31 where it is ignited.

IV hen the carbid in the container 11 becomes exhausted, the knob 24 isirst operated to actuate the rod 21 and shut off the supply of water tothe container 11v and the knob 29 is then actuated to operate the rod 27thus permitting Water in the compartment 15 to liow into thevauxiliarycontainer or compartment 16 where gas will be produced by the action ofthe water and the carbid contained in the compartment 16, the said gasbeing then adapted to pass outfilled a light can be produced at tbeburner v 32 byl permitting vWater from the comparting desirable toretain a use.

iyardly Athrough the burner 82 Where the same is ignited. Thus it willbe seen that While the carbid container ll is being re- .ment l5 to flowintothe auxiliary carbid container of my lamp and container has been`properly refilled and connected to the bodyl() the Wat-er supply -totbe compartment 16 can be shut ont by operating the knob 29 and then byturning the knob-24 Water will again tloW into the carbid container l1,.thus producing new gas in the said container, the said gas beingadapted to l'oW outwardly through the burner 31. v

VMy device is particularly adaptable for use in connection with minerslamps, it belight in these kind of lamps at all times when the same arein Having tlius fully described the invention, What`l claim as new, is

1. A lamp comprising a body, a carbid container for removable connectionwith the said body, a partition formed in the said body to constitute aWater compartment and an auxiliary carbid container, burners connectedWith the said carbid container and said auxiliary carbid container,means tor after the carbidl :imacat supplying Water to the said carbidcontainer and means for supplying water to the said auxiliary carbidcontainer. c 2. A lamp comprising a body, a carbid .container forremovable connection With formed in thev said body to constitute a Watercompartment and an auxiliary carbid container and lapertiired tubes thesaid body, a partition extending from the said Water compartment to thesaid carbid container and said `auxiliary carbid container for supplyingWater thereto.

3. A lainp comprising a body, a 'carbid container for removableconnection with Vtlie said body, a partition formed in the said body toconstitute a Water compartment and an auxiliary carbid container, meansfor supplying Water to the said carbid container, ineansl for supplyingWater to the said auxiliary carbid container, an adjusting screw forcontrolling the supply of water to the said carbid' container and asecond screw for controlling the supply off Water to the said auxiliarycarbid container. In testimony whereof I aflix my 'signature Iinpresence of tWo Witnesses. l
